Abstract:
Bentonite samples collected from M'Zila of Mostaganem (Algeria) were treated in first protocol with sulfuric acid at concentrations 1, 3 and 6N. The second protocol concerns the acid attack of bentonite combined with thermal treatment at temperatures of 100 and 200 °C. The obtained adsorbents were characterized by different analyses techniques such as chemical composition, X-ray diffraction (XRD), specific surface area and pHPZC. The modified bentonites were used for removal of Chlorothalonil (Chl) from aqueous solution. The adsorption behavior of the pesticide was studied under different experimental conditions of pH, contact time, concentration of Chl and temperature of solution. The adsorption of Chl followed pseudo-second order kinetics and was described by the Freundlich equation. Thermodynamic study revealed that Chl adsorption was endothermic and physical in nature.
